Hi friends,

I have a matrix of dimension (2541 x 1). I need to rewrite this matrix into (121 x 21)
The first 121 elements in matrix one will be the first row in second matrix and so on....

remember 121 x 21 =2541

please can someone help me...

thanks in advance...

cheers

You are looking to change the 'shape' of the array. i.e reshape it.

http://www.mathworks.com/support/
Right side search box, choose documentation from the drop down
Search for 'reshape array'

And then, you might also transpose/shiftdim/permute
